* You should know something about your system, perhaps by having
31
* a manual handy, when you edit this file. You should copy config.h-dist
32
* to config.h, and edit config.h. Do not modify config.h-dist, so that
33
* it will be easy to apply any patches that may be distributed.
35
* The general idea is that systems conforming to the various standards
36
* should need to do the least amount of changing. Definining the various
37
* items in ths file usually means that your system is missing that
40
* The order of preference in standard conformance is ANSI C, POSIX,
43
* If you have no clue as to what's going on with your system, try
44
* compiling gawk without editing this file and see what shows up
45
* missing in the link stage. From there, you can probably figure out
46
* which defines to turn on.

* If you have a 4.2 BSD vintage system, then the strftime() routine
171
* supplied in the missing directory won't be enough, because it relies on the
172
* tzset() routine from System V / Posix. Fortunately, there is an
173
* emulation for tzset() too that should do the trick. If you don't
174
* have tzset(), define this.

199
